- Vacheron Constantin has continued its 270th anniversary celebrations with the debut of the Overseas Grand Complication Openface, the watchmakerโs most complicated sports watch ever.
- Entirely crafted from grade 5 titanium, the watch features a minute repeater, perpetual calendar, tourbillon, and skeletonised dial.
- The watch is not a limited edition, but will be in โlimited productionโ.
Regular Boss Hunting readers will already know itโs the 270th anniversary of Vacheron Constantin, and in the brandโs continued celebrations, the Swiss watchmaker has unveiled the most technically ambitious sports watch to date: the Overseas Grand Complication Openface. Crafted entirely from grade 5 titanium, this jaw-dropping piece is the first Overseas to feature a minute repeater, bringing the zenith of high horology into a watch thatโs made for action.
Housed in a surprisingly slim 13.1mm profile (considering its shopping list of functions), the 44.5mm case surrounds a skeletonised dial showcasing a minute repeater, a perpetual calendar, and a tourbillon โ all of which are delivered via the hand-wound 58-hour power reserve calibre 2755 QP. This movement, which made its debut in 2005, comprises no less than 602 meticulously hand-finished components and arrives complete with the Geneva Seal.
Despite housing a minute repeater โ a complication notoriously fussy when it comes to water โ Vacheron took a year to reengineer the system from scratch to ensure 30 metres of water resistance. This rating is still achieved despite the minute repeating slide and the crown, which doesnโt screw down, both of which present as potential points of moisture ingress.
As the name suggests, the dial is semi-transparent, with floating registers that reveal glimpses of the movement beneath, making for a watch thatโs equally about the visual architecture as it is about its undeniable mechanical firepower. Paired with a titanium bracelet that matches the case, prospective owners can expect the same ergonomic presence on the wrist as offered by other references within the Overseas collection.
Itโs an interesting watch, not just because of how technically sophisticated it is, but because of the lifestyle-focused format it arrives in. The Overseas Grand Complication Openface is equal parts a statement of watchmaking expertise and a holy grail for Vacheron Constantin collectors, cementing it as one of the most impressive watches thatโs likely to be released in 2025.
While not strictly a limited edition, production of this watch will be limited due to the movementโs complexity and the challenge of producing it. As for how deep your pockets need to be to get one on your wrist, the RRP is unsurprisingly POA.
